Designed for long-distance observations by law enforcement, military, and tactical professionals, and engineered to exacting military specifications for outstanding performance in challenging light and environmental conditions, theSteiner Optics 20x80 M2080 Military Binocularscombine multiple technologies and features to ensure clear and crisp views from first light through to twilight and everything in between.
Their performance starts with the combination of powerful magnification and over-sized objectives. At 80mm the objectives draw in the copious amounts of light required for seeing in low light, or in heavy fog and cloud cover; while the 20x power brings distant subjects in close for detailed observations. The optics are fully multi-coated to maximize light transmission through the light path, with a wide angle of view to provide sweeping views despite the high power, while helping to minimize the discomfort often associated with using optics on rough or rolling seas. All of these features, when coupled with the traditional Porro prism light path, present the user with an immersive observational experienced defined by bright and clear high-contrast views and accurate color rendition.
Complementing the optical performance are construction details that allow the binoculars to withstand the rigors of the outdoors. These details begin with Steiner's Sport -Auto-Focusing System which allows the user to focus each eyepiece, just one time, and eliminates the need to refocus again regardless of how near or far the subject is - or if it is moving. The chassis is made of a lightweight and impact-resistant Makrolon polycarbonate material that is wrapped in an oil-, petroleum-, and chemical-resistant NBR synthetic rubber armor that offers improved grip security, especially in cold and wet weather. Their optical tubes are nitrogen-filled and O-ring sealed to be waterproof to a depth of 16 feet, and resistant to internal fogging when moving through extreme temperature changes and environmental conditions. Because of the challenges posed by hand-holding large and powerful optics, Steiner includes a tripod adapter that clamps anywhere along the center stabilizer bar to steady the view and relieve arm fatigue.
High 20x power greatly magnifies objects for detailed observation of distant objects
Large oversized 80mm objective lenses draw in copious amounts of light to ensure bright and clear images, while enhancing its low-light capabilities through the pre-dawn and dusk hours, and in heavy fog or cloud cover
Traditional Porro prism optical path produces a rich depth of field to more easily discern the relative distances between objects in the field of view
Floating prism mounting system helps to absorb impacts to avoid damage and maintain optical path collimation
Anti-reflection fully multi-coated optics maximize light transmission, improve color rendition accuracy, enhance contrast, and improve clarity
Wide 66° apparent angle of view provides sweeping views to complement the high-power, and helps to minimize the disorientation often associated with using high-power optics on rough or rolling seas
